HEIGHT GAUGE Alfred Deakin, Detroit, Mich.

Application August 23, 1949, Serial No. 111,780

(Cl. Sli- 171) 1 Claim. 1

This invention relates to a height gauge the object being to provide a new and improved form of gauge including a floating scriber useful in determining fractional heights relative to a base line and may also be used as a checking gauge.

In the drawing:

Fig. 1 is a side elevation of my improved gauge.

Fig. 2 is a section taken on line 2-2 of Fig. l.

Fig. l3 is an enlarged section taken on line 3-3 of Fig. 2.

Fig. 4 is a section taken on line 1%-4 of Fig. 3.

The gauge according to my invention includes the base member I on the upper surface of which is a plate 2 secured in position by the screws 3. Secured to the plate 2 is a vertical standard 4 of thin sheet material and having graduations in inches and slidable on the standard 4 is a member 5 having a slot 6 in one face thereof through which the graduations on the standard may be observed. The member has a threaded aperture on one side to receive a screw I which engages an edge of the vertical member Il and the opposite side of the member 5 has a screw 8. The slidable member 5 has a slot 9, as shown in Figs. 1 and 3, and in the slot 9 is one end of a member I6 which is pivoted on 'the pin II on member 5 and a leaf spring I2 has one end seated in the upper edge of the inner end of the member I6 and the free end of the spring engages the inner face of the head of the screw 8. The member I6 has an upwardly extending arm I3 which is held in engagement -with the outer face of the head of the screw 8 by the spring I2 and by turning the head of the screw 8 the member I6 is turned on the pin II as an axis.

On the outer end lli of the member I is a U-shaped member I5, shown more clearly in Fig. 3, and a headed screw I6 has a threaded end in a threaded aperture provided therefor in the base of the U-shaped member I for operative engagement with member I6 to secure member I5 in position thereon. Loosely pivoted between the two sides of the U-shaped member is a scriber Il having a pointed end I8 as shown more clearly in Fig. 1.

The slidable member 5 has in one face thereof graduations I9 and 26 on the opposed longitudinal edges of the slot 6. The standard 4 has transverse lines 1 to 10 inclusive in parallel relation which are one inch apart and the longitudinal side edges of the `slot B are calibrated as may be desired, as for instance in inches and fractions of an inch.

Inuse of the device the base I is positioned on a flap supporting surface and the' member 5- is movable longitudinallyY of the standard 4 to position the point I8 of the scriber practically in contact with the element to be measured and, by loosening the screw 1, the member 5l may be moved longitudinally to position the point I8V practically in contact with the said element as indicated by dotted lines I9 in Fig. l.

It is further to be understood' that the point I8 of the member Il may be utilized to determine the distance of a mark or' slot on one side of the element I9' from the surface onl which it is positioned. The head of the screw S is positioned between the end of the spring I2 and arm I3 of the member I6. By such arrangement the pivoted member I6 is always held from accidental movement.

Operation When used as a scriber to mark a longitudinal line upon the vertical side wall of an object, both the object and the base I are positioned upon a flat surface. Assuming it is desired to scribe a horizontal line upon the sidewall of the object one inch up from its bottom, a conventional accurate gauge block of cubical shape and of a predetermined one inch height is positioned upon base I directly under the arm. Il.

Thereafter the member 5 is released by loosening screw I and dropped until scriber I'I engages and levels itself upon the top surface of the particular gauge block, and by virtue of its pivotal mounting I I the scriber levels down upon the top surface of said block, after which the screw 1 is tightened.

The screw 8 is then turned counter-clockwise so that it moves outwardly against the arm I3 of member I0 effecting a slight counter-clockwise pivoting movement of the scriber support ID to exert a downward pressure upon the scriber for holding the same in a horizontal position snugly against the top surface of the gauge block or blocks which may be employed, depending upon the desired height.

The scriber tip I8 is positioned below the bottom surface of the central portion of the scriber a distance exactly equal to the height of the base I so that it is known that the tip I8 is positioned relatively to the object to be scribed at the same height as the height of the gauge block or stacked gauge blocks mounted on base I directly below said scriber. The base I is then slid along the flat surface upon which it is supported with the scriber tip I8 bearing against the vertical wall of the object to thereby mark a line'thereon which is, when using a one inch gauge block, one inch in height from the base of the body.

As screw I6 bears against the top surface of member l0, it is apparent that turning of said screw would cause member Il and its support I5 to move upwardly, with member I1 possibly contacting member l0, if desired. Under some conditions this may not be necessary if a gauge block of cubical form is used, as such a block would in eiect freeze the free swinging motion of scriber bar I1. However, with screw I6 tightened, bar l1 would engage member I0 so that outward adjustment of screw 8 would effect a counter-clockwise pivotal movement of member I0 tending to move bar l1 tightly down upon the gauge block.

It is believed obvious from the foregoing description that the device is comparatively simple in construction and Well adapted for the purpose described.

Having thus briefly described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is:

In combination, a ilat base, an upright standard secured thereon, a member slidably mounted upon the standard, an adjustable set screw on said member engageable with said -standard for securing said member in vertically adjusted position, a scriber support pivotally mounted at one endupon said member at one side of said standard, a set screw with its stem threadably mounted on said member and with its head retainingly engaged by said support upon one side thereof, a spring interposed between the other side of said head and said support, whereby rotation of said latter set screw effects pivotal movement of said support, an inverted U-shaped element slidably positioned over the outer end of said support, a set screw on said element engageable with said support, and an elongated scriber centrally positioned within the ends of said element and pivotally and loosely mounted thereon, adapted to bear upon a gauge block of predetermined height upon said base.
